JACC This Week

In this podcast, Dr. Valentin Fuster discusses a groundbreaking study by Dr. Anna Barton and her team on myocardial fibroblast activation following acute myocardial infarction. Using advanced imaging techniques, the research uncovers how fibroblast activity plays a critical role in heart remodeling, revealing that fibrosis is dynamic and may offer new therapeutic opportunities for preventing heart failure and improving long-term recovery after heart attacks.

In this podcast, Dr. Valentin Fuster discusses a study on the use of the microaxial flow pump (Impella) in treating older patients with cardiogenic shock following a myocardial infarction. The findings suggest that while the Impella pump can reduce mortality in younger patients, its effectiveness diminishes in those over 77, highlighting the need for age-based patient selection to optimize outcomes in this complex condition.

In this podcast, Dr. Valentin Fuster discusses a study examining the impact of short-term ozone exposure on arterial stiffness and cardiovascular health. The research reveals that ozone may reduce oxygen availability, triggering compensatory responses like increased red blood cell count, which contributes to arterial stiffness, and emphasizes the need for further research into the biological mechanisms linking ozone exposure to cardiovascular diseases.

In this podcast, Dr. Valentin Fuster introduces a detailed review on managing coronary stent under-expansion, a critical issue that increases risks like restenosis and myocardial infarction. The discussion highlights the causes, challenges, and treatment strategies for under-expanded stents, emphasizing the importance of intravascular imaging and individualized approaches to optimize patient outcomes.

In this episode of JACC, Dr. Valentin Fuster explore the 2024 ACC Expert Consensus on arrhythmia monitoring following a stroke, outlining critical insights on stroke types, arrhythmia detection, and anticoagulation strategies. The discussion highlights the complexities of identifying atrial fibrillation post-stroke and the challenges of choosing optimal antithrombotic therapy in diverse stroke cases.

Don't miss this new editorial from Harlan M Krumholz, MD, SM, FACC, FAHA, and Joshua D. Wallach, PhD, MS, which discusses the transformative role of preprints in scientific publishing, particularly in cardiovascular research, highlighting their potential to accelerate discoveries, foster collaboration, and increase transparency. It outlines the updated policy of the JACC that encourages authors to post preprints before submission, emphasizes transparency and version control, and integrates with medRxiv for seamless submission processes. The piece also addresses concerns about preprints, emphasizing their rigorous screening process and the benefits for authors in terms of visibility, feedback, and research quality.
